I have Sleep Apena. I bought this mask to place under my breathing mask at night. It does help keep my eyes from drying out at night. However following directions I only ware it 2-3 times per week-all night long. I have worn it now 5x's. I noticed it has decreased my crows feet Fine lines. It has reduced puffyness, and softened a few lines under my eyes. I'm in my 50's, Apena masks create horrible lines and wrinkles. I wish they made a full face mask. I use this mask and a Cupron Mask to help prevent more wrinkles. So far- This mask is very soothing, comfortable and seems to be keeping wrinkles from increasing. I wish I knew if I can continue to use it after the 20 times.- No one seams to know. Gave it 4* due to it's cheeper elseware. But I like ezpay and I like the product-It's helping me.
